Invoicing and Payments

Overdue invoice reminders

Mallow automatically marks past-due invoices as "overdue" in your portal and sends reminder emails on a fixed schedule. This process runs in the background so you don't need to manually follow up on unpaid invoices.

When an invoice becomes overdue

An invoice is marked overdue when its due date has passed. Mallow checks for qualifying invoices and updates each status automatically.

Reminder schedule

Overdue reminder emails are sent the day after the due date and repeat every 7 days while the invoice remains unpaid. The system uses an internal log to avoid sending duplicate reminders, so each invoice only receives one reminder per cycle.

Sending additional reminders

You can manually trigger additional past-due reminder notifications by clicking on the three dots next to the invoice and selecting "send reminder" from the drop-down menu. This will tell our system to send another reminder email right away.

Who receives the reminders

Each reminder is sent to two groups:

  • Your client — the email address on the invoice

  • Your internal team — the team email associated with the account

How this fits with other automated emails

Subscription and recurring invoices already send renewal notifications, receipts, and billing reminders automatically. Overdue reminders are a separate follow-up flow that applies only to invoices that have not been paid by the due date.
